CBC Ottawa ran two pieces on Bill yesterday.
Alan Neal had Bruce Cockburn and Sneezy Waters on All in a Day to discuss Bill. You can listen to that here.
And the 6pm News on CBC ran a short story on Bill built around an earlier 2008 profile. The 2008 profile can be viewed here, and the newer piece begins at 37:00 here.
And from the Ottawa Sun, a profile from 1997 here.
